Zerkalnaya Cove, Coastal inlet in Primorsky Krai, Russia.

Zerkalnaya Cove is a coastal inlet along the Sea of Japan in Primorsky Krai. The waters are ringed by steep mountains and rocky outcrops that rise directly from the shore.

Until 1972 the cove was known as Tadushi; it was then renamed Zerkalnaya, the name it shares with the river entering its head and with the nearby village of Zerkalnoye in Kavalerovsky District. The cove lies between Cape Zerkalny to the north and Cape Vystup to the south, and its shores were already described in Russian sailing directions, which use the yellow scree on Cape Vystup and the 6 m rock off Cape Zerkalny as landmarks.

The cove was called Tadushi until 1972, when it was renamed Zerkalnaya, mirror, after the river and the freshwater Lake Zerkalnoye in its lower valley. Tourist complexes stand on the shores of both the lake and the cove, and in summer many local holidaymakers come here. In winter, when the cove does not freeze, the river mouth draws ice fishermen.

Access is via hiking trails from nearby settlements that vary in difficulty. Summer months from June through September offer the best visiting conditions with stable weather and clear trails.

The Zerkalnaya River splits into two arms at its mouth, which rejoin before entering the cove through a single channel 25 to 30 metres wide. A separate unnamed stream up to 3 metres wide enters the cove in its southern part.
